13:06 Support #1338: Release CoCoALib-0.99700

- I suggest putting the SHA-256 checksum in the "Notes" section on the web page for source releases.
Probably the best...

22:28 Bug #1264 (Closed): Remove unnecessary files before making CoCoALib release TGZ files
- John checked

It does highlig... -

- adjusted the page and the release-xxx.sh file to produce the correct files and instructions for publishing.
-
- I think I might be slightly confused. What I wrote above in comments 11 and 12 actually refers to the "binary" relea...

I have added a line after the @MakeTGZ@ line:... -

-
- Many useful GFan-based functions are implemented in CoCoA-5.
Port them into CoCoALib.

- updated starting page: https://cocoa.dima.unige.it/redmine/

If first row of M all positive

M 0

I had some problems in finding the correct functions to make the matrix.

- If we want to do this, we should delay the release a few days, so we can find out what to do.

-
- It seems to rebuild dependencies only in @src/tests/@.
Too tired to investigate now :-(
-
- It seemsthat the main @Makefile@ does not rebuild dependencies after a @make veryclean@.
Investigate & fix.
-
- *IMPORTANT* When the task is almost finished, we must review the impl of *@SparsePolyRingBase::IdealImpl::myGBasis@*.
